CYLINDER MORE PARTICULARLY THOSE FOR COMBUSTION ENGINES.

Application filed March 28, 1923.

To all whom it may concern:

Be it known that I, OHN CAMPBELL Mao- CALL MAoLAoAN, a subject of theKing of Great Britain and Ireland, and a resident of Drumchapel,Scotland, have invented certain new and useful Improvements in CylindersMore Particularly Those for Combustion Engines, of which the followingis the specification.

The invention relates to that type of double-acting cylinder moreparticularly for use in internal combustion engines in which is a trunkpiston operated by a gudgeon pin passing out through gaps in thecylinder walls, and has for its object a cylinder of this .type ofimproved and simplified construction in which are obtained certainadvantages such as lightness.

A cylinder element made according to the invention comprises essentiallytwo end members connected together at their inner ends by a separate andcomparatively light structure permitting of the protrusion of thegudgeon pin. 7

This light structure consists of a series of links-for example, twodiametrally opposite-lying parallel with the axis of the cylinder partsexternal to them, and pivoted at their ends upon them. The links mayhave either cylindrical or spherical bearings at their points ofpivoting and may be. provided with means for the adjustment of theirlength.

An example of the carrying out of the invention is shown on twoaccompanying sheets of explanatory drawings in which Figures 1 and 2 arediagrammatic elevations at right angles to one another of the twocylinder end members of a cylinderelement with their connecting means,while Figure 3, Sheet 2, is a sectional elevation to an enlarged scaleof a unit of the connecting means.

In this example the cylinder end members 10 are connected with oneanother by Serial No. 628,233.

two diametrally opposed links 11 lying parallel with the axes of thecylinder parts, external to them, and pivoted at their ends upontrunnions 12 which may be either formed upon or secured to the cylinder.

According to an example of these links which is shown in Figure 3, thetrunnions 12 are in this instance formed upon rings 13 embracing theinner ends of the cylinders 10 while the ends of the links 11 carry endcaps 14 through which they pass with clearance and which end caps,spherical in-.

l. A cylinder element more particularly for combustion enginescomprising two end members connected together. at their inner ends by aseparate structure consisting of a series of links.

2. A cylinder element'more particularly for combustion engines,comprising two end members connected at their inner'ends by'twodiametrically opposed links lying parallel with its axis. r

3; A connecting link for the cylinder element forming the subject-matterof the foregoing claimshereoz havingbetween its ends and the cylinderend members coacting spherical elements.

In testimony whereof I have signed my name to this specification.

JOHN CAMPBELL MAGOALL MACLAGAN.
